Title: Diversion of gas escaping from reservoir if accident occurs - where escaping gas is liquefied by refrigerant and fed into storage tank
Inventor: FRANK KARL ING GRAD
IPC: F25J3/02
Filed: 1980-03-24
Abstract: Stored material consists esp. of fetid-, and/or toxic-, and/or corrosive gas, a noble gas, or a volatile liq. If gas or vapour escapes from a reservoir, it is cooled to below its b.pt. via a refrigerant consisting of liq. CO2, or a liq. gas with a low b.pt.; and the liquefied gas thus obtd. is fed into a tank. The liq. in tank may be returned to the initial reservoir, or re-evaporated and burnt in a flare. The pref. plant consists of a reservoir with a safety valve leading to a heat exchanger cooled via liq. CO2, so gas escaping via the safety valve flows as a liq. into a tank provided with an expansion chamber and a flare stack. A high degree of safety is provided at low cost; and the escaping gas can be reclaimed.

Patent DE-3128661-A1 (DE)
Title: Foot loop on windsurfing boards
Filed: 1981-07-20
Abstract: The foot loops consisting of a strap band (4) are connected at least at one of their ends to the windsurfing board (1) by means of a device (5) which releases the end of the strap band (4) like a safety binding if a certain moment is exceeded. Here, the end of the strap band (4) is connected to the device (5) via a spindle (8, 52). The device (5) is designed in such a way that motion components perpendicular to the top surface (3) of the windsurfing board (1) correspond almost in their possible release moment to a rigid connection with the windsurfing board, whereas in the case of component motions acting in the plane of the top surface (3) the release moment drops towards zero. In a first embodiment, the spindles (8) engage here via shaped bodies (14, 14') in recesses (15) in the side walls (11, 2) of a housing set in the windsurfing board (1). The shaped bodies (14, 14') are under adjustable spring pretension of a spring element (31). The top edge (17) of the recesses (15) is designed here in such a way that there is an almost insurmountable projection for the spindles (8) in a centre area (17), whereas in lateral positions, which correspond to a rotary component, the recess (15) is virtually open to the top. In a second embodiment, the ends of the spindles (52) are mounted in guideways (55) which form inclined planes and lead to an opening (57) leading at the top out of a housing (51). In the case of loads perpendicular to the top surface (3), the spindles are therefore completely held in place, whereas in the case of rotary components at least one of the ends of the spindles (52) can come out of the opening (57). <IMAGE>

Title: Vertically adjustable slab bearing, in particular for balcony and terrace coverings
Inventor: MEYER JUERGEN DIPL ING
IPC: E04F15/024
Filed: 1982-07-13
Abstract: Stilted bearings which, provided with threads, wedges and screws for the most part, ensure compensation of the slab differences, which are however insignificantly small. The abovementioned slab bearing, however, consisting of a straight upper slab, a subdivided wedge-shaped lower slab and an intermediate displaceable double-knob part, ensures compensation of the considerable unevennesses of the foundation (bonding detachments etc.). The upper part (slab-supporting surface) remains level and thus automatically produces straight alignment of the surface.
